2021-06-24Kernel: Move special sections into Sections.hHendiadyoin1
This also removes a lot of CPU.h includes infavor for Sections.h
2021-06-24Kernel: Remove unused CPU.h includesHendiadyoin1
In most cases we did not need it at all, in other, we only needed one header from it
2021-06-17Kernel/Interrupts: Return boolean on whether we handled the interruptLiav A
If we are in a shared interrupt handler, the called handlers might indicate it was not their interrupt, so we should not increment the call counter of these handlers.
2021-06-17Kernel/Interrupts: Enumerate nested handlers in a shared handlerLiav A
When asked to enumerate all interrupt handlers, display all shared handlers within it instead of just returning the responsible handler of them.
2021-04-22Everything: Move to SPDX license identifiers in all files.Brian Gianforcaro
SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
2021-03-21Kernel::CPU: Move headers into common directoryHendiadyoin1
Alot of code is shared between i386/i686/x86 and x86_64 and a lot probably will be used for compatability modes. So we start by moving the headers into one Directory. We will probalby be able to move some cpp files aswell.
2021-03-12Kernel: Convert klog() => AK::Format in SharedIRQHandlerAndreas Kling
2021-02-28Kernel: Fix GenericInterruptHandler problems with virtual functionsTom
Because registering and unregistering interrupt handlers triggers calls to virtual functions, we can't do this in the constructor and destructor. Fixes #5539
2021-02-23Everywhere: Rename ASSERT => VERIFYAndreas Kling
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED) Since all of these checks are done in release builds as well, let's rename them to VERIFY to prevent confusion, as everyone is used to assertions being compiled out in release. We can introduce a new ASSERT macro that is specifically for debug checks, but I'm doing this wholesale conversion first since we've accumulated thousands of these already, and it's not immediately obvious which ones are suitable for ASSERT.
2021-02-19Kernel: Slap UNMAP_AFTER_INIT on a bunch more functionsAndreas Kling
We're now able to unmap 100 KiB of kernel text after init. :^)
2021-02-08Everywhere: Replace dbgln<flag>(...) with dbgln_if(flag, ...)AnotherTest
Replacement made by `find Kernel Userland -name '*.h' -o -name '*.cpp' | sed -i -Ee 's/dbgln\b<(\w+)>\(/dbgln_if(\1, /g'`
2021-01-26Meta: Split debug defines into multiple headers.asynts
The following script was used to make these changes: #!/bin/bash set -e tmp=$(mktemp -d) echo "tmp=$tmp" find Kernel \( -name '*.cpp' -o -name '*.h' \) | sort > $tmp/Kernel.files find . \( -path ./Toolchain -prune -o -path ./Build -prune -o -path ./Kernel -prune \) -o \( -name '*.cpp' -o -name '*.h' \) -print | sort > $tmp/EverythingExceptKernel.files cat $tmp/Kernel.files | xargs grep -Eho '[A-Z0-9_]+_DEBUG' | sort | uniq > $tmp/Kernel.macros cat $tmp/EverythingExceptKernel.files | xargs grep -Eho '[A-Z0-9_]+_DEBUG' | sort | uniq > $tmp/EverythingExceptKernel.macros comm -23 $tmp/Kernel.macros $tmp/EverythingExceptKernel.macros > $tmp/Kernel.unique comm -1 $tmp/Kernel.macros $tmp/EverythingExceptKernel.macros > $tmp/EverythingExceptKernel.unique cat $tmp/Kernel.unique | awk '{ print "#cmakedefine01 "$1 }' > $tmp/Kernel.header cat $tmp/EverythingExceptKernel.unique | awk '{ print "#cmakedefine01 "$1 }' > $tmp/EverythingExceptKernel.header for macro in $(cat $tmp/Kernel.unique) do cat $tmp/Kernel.files | xargs grep -l $macro >> $tmp/Kernel.new-includes ||: done cat $tmp/Kernel.new-includes | sort > $tmp/Kernel.new-includes.sorted for macro in $(cat $tmp/EverythingExceptKernel.unique) do cat $tmp/Kernel.files | xargs grep -l $macro >> $tmp/Kernel.old-includes ||: done cat $tmp/Kernel.old-includes | sort > $tmp/Kernel.old-includes.sorted comm -23 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.new comm -13 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.old comm -12 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.mixed for file in $(cat $tmp/Kernel.includes.new) do sed -i -E 's/#include <AK\/Debug\.h>/#include <Kernel\/Debug\.h>/' $file done for file in $(cat $tmp/Kernel.includes.mixed) do echo "mixed include in $file, requires manual editing." done
2021-01-25Everywhere: Debug macros instead of constexpr.asynts
This was done with the following script: find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/dbgln<debug_([a-z_]+)>/dbgln<\U\1_DEBUG>/' {} \; find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/if constexpr \(debug_([a-z0-9_]+)/if constexpr \(\U\1_DEBUG/' {} \;
2021-01-25Everywhere: Remove unnecessary debug comments.asynts
It would be tempting to uncomment these statements, but that won't work with the new changes. This was done with the following commands: find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec awk -i inplace '$0 !~ /\/\/#define/ { if (!toggle) { print; } else { toggle = !toggle } } ; $0 ~/\/\/#define/ { toggle = 1 }' {} \; find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec awk -i inplace '$0 !~ /\/\/ #define/ { if (!toggle) { print; } else { toggle = !toggle } } ; $0 ~/\/\/ #define/ { toggle = 1 }' {} \;
2021-01-25Everywhere: Use CMake to generate AK/Debug.h.asynts
This was done with the help of several scripts, I dump them here to easily find them later: awk '/#ifdef/ { print "#cmakedefine01 "$2 }' AK/Debug.h.in for debug_macro in $(awk '/#ifdef/ { print $2 }' AK/Debug.h.in) do find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/#ifdef '$debug_macro'/#if '$debug_macro'/' {} \; done # Remember to remove WRAPPER_GERNERATOR_DEBUG from the list. awk '/#cmake/ { print "set("$2" ON)" }' AK/Debug.h.in
2021-01-22Everywhere: Replace a bundle of dbg with dbgln.asynts
These changes are arbitrarily divided into multiple commits to make it easier to find potentially introduced bugs with git bisect.
2020-12-02Kernel: Fix counting interruptsTom
Move counting interrupts out of the handle_interrupt method so that it is done in all cases without the interrupt handler having to implement it explicitly. Also make the counter an atomic value as e.g. the LocalAPIC interrupts may be triggered on multiple processors simultaneously. Fixes #4297
2020-08-30Kernel: Unbreak building with extra debug macros, part 1Ben Wiederhake
2020-08-28Kernel: Remove the enabled concept of IRQ handlersLiav A
An IRQ handler should always be ready to respond to any IRQ. We must remember that hardware can generate IRQs without any interaction from our code at all. Ignoring IRQs in such cases is obviously not the right thing to do.
2020-03-24Kernel: Abstract IRQ controller handling from Interrupt handlersLiav A
Now we don't send raw numbers, but we let the IRQController object to figure out the correct IRQ number. This helps in a situation when we have 2 or more IOAPICs, so if IOAPIC 1 is assigned for IRQs 0-23 and IOAPIC 2 is assigned for IRQs 24-47, if an IRQHandler of IRQ 25 invokes disable() for example, it will call his responsible IRQController (IOAPIC 2), and the IRQController will subtract the IRQ number with his assigned offset, and the result is that the second redirection entry in IOAPIC 2 will be masked.
2020-03-19Kernel: Use a const reference to RegisterState in IRQ handlingLiav A
2020-03-02Kernel: Use klog() instead of kprintf()Liav A
Also, duplicate data in dbg() and klog() calls were removed. In addition, leakage of virtual address to kernel log is prevented. This is done by replacing kprintf() calls to dbg() calls with the leaked data instead. Also, other kprintf() calls were replaced with klog().
2020-02-29Kernel: Simplify interrupt managementLiav A
The IRQController object is RefCounted, and is shared between the InterruptManagement class & IRQ handlers' classes. IRQHandler, SharedIRQHandler & SpuriousInterruptHandler classes use a responsible IRQ controller directly instead of calling InterruptManagement for disable(), enable() or eoi(). Also, the initialization process of InterruptManagement is simplified, so it doesn't rely on an ACPI parser to be initialized.
2020-02-29Kernel: Delete unnecessary register & unregister callsLiav A
2020-02-24Kernel: Add SharedIRQHandler classLiav A
This class represents a shared interrupt handler. This class will not be created automatically but only if two IRQ Handlers are sharing the same IRQ number.
